The ODH of ethylbenzene to styrene was investigated over different loadings of V2O5 (5-30 wt.%) supported on HMS embedded with Zr. The all prepared materials were tested for their performance with environmentally friendly carbon dioxide as soft oxidant. All the prepared catalysts were treated by hydrothermal and microwave methods. The catalysts were characterized by XRD, IR, TPD, BET and TEM. With comparing the different loadings of the catalysts we found that the most active loading is 20% of V2O5/ZrO2-HMS microwave treated (V/ZHMSMW3). The catalyst V/ZHMS-MW3 exhibited higher activity among the all prepared catalysts. Maximum conversion of ethylbenzne 82.44, yield 82.19 and selectivity 99.75 for styrene were obtained by V/ZHMS-MW3.
